The Purdue Peace Project (PPP), a locally-led peacebuilding initiative, is a pioneer in the field of peacebuilding. It is the only university-based political violence prevention initiative that does peacebuilding work in fragile states and does empirical research to advance knowledge about political violence prevention at the local, community level.

Frontier worked with the PPP to develop a scalable and repeatable approach for evaluating the cost-effectiveness of peacebuilding activities. This included an extensive literature review, data analysis, and interviews with experts in peacebuilding, economics and conflict.
